According to a study done by de anza students, the height for asian adult males is normally distributed with an average of 66 inches and a standard deviation of 2.5 inches. suppose one asian adult male is randomly chosen. let x = height of the individual. a) give the distribution of x.
x ~
b) find the probability that the person is between 64 and 69 inches.
write the probability statement.

what is the probability?

  A)

B)0.6731

Step-by-step explanation:

Given : The height for Asian adult males is normally distributed with

Mean :

Standard deviation :

Let X = height of the individual.

A) The distribution of X is given by :-

B) The formula to find the z-score is given by  :-

For , x= 64

For , x= 69

Now, the required probability :-

Hence, the probability that the person is between 64 and 69 inches is 0.6731.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

the answer is stop cheating on things stoopid
